Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1 This invention discloses a laser processing device, including a housing 1. The housing 1 includes a processing section 11 and an auxiliary section 12. Please refer to [link to relevant documentation]. Figure 2 The machining section 11 is equipped with a movable axis assembly 2, which includes a Z-axis section 21 and a Y-axis section 22 fixedly mounted on the machining section 11. An X-axis section 23 is slidably mounted on the Y-axis section 22. Drive motors are installed on the Z-axis section 21, Y-axis section 22, and X-axis section 23. (Please refer to...) Figure 3 The processing section 11 is equipped with a laser assembly 3. Please refer to [link / reference]. Figure 4 The laser assembly 3 includes a laser head 31, which is slidably mounted on the X-axis section 23. The drive motor of the X-axis section 23 drives the laser head 31 to slide. Please refer to [link to relevant documentation]. Figure 2 The Z-axis section 21 is slidably mounted with a perforated base plate 4. The drive motor of the Z-axis section 21 drives the perforated base plate 4 to slide. Please refer to [link to relevant documentation]. Figure 5 The auxiliary part 12 is equipped with a cooling assembly 5, which includes a cooling pipe installed on the laser assembly 3. The auxiliary part 12 also has a filter box 61, which includes a filter screen 611, an activated carbon box 612, and a filter element box 613. A filter fan 62 is installed at the lower end of the filter box 61, and a pipe runs through the exhaust port of the filter fan 62 through the housing 1. The processing part 11 is fixedly equipped with a back plate 63, with a movable shaft assembly 2 located on one side of the back plate 63. The back plate 63 has arrayed air outlets connected to the upper end of the filter box 61 via pipes. A hinged upper cover 13 is provided at the upper end of the processing part 11, with the movable shaft assembly 2 located below the upper cover 13. (See also...) Figure 2 The processing unit 11 is equipped with a control module 7, which is connected to the laser assembly 3, the moving axis assembly 2, the cooling assembly 5, and the filter fan 62.

[0037] Specifically, a back plate 63 is provided at the processing section 11, so that the back plate 63, the processing section 11, and the upper cover 13 form a relatively closed processing space in the processing area where the moving shaft assembly 2 is located. The back plate 63 is connected to the filter box 61 and the filter fan 62 through a pipe. The dust generated during processing is filtered through the filter screen 611, the activated carbon box 612, and the filter element box 613.

[0038] In this way, by setting up the filter box 61 to filter the smoke and dust generated during laser processing, the harm of smoke and dust can be reduced.

[0039] In some feasible embodiments, both the processing unit 11 and the auxiliary unit 12 are rectangular shells. The bottom of the auxiliary unit 12 is equipped with casters 8. The moving axis group 2 controls the lifting and lowering of the porous base plate 4 through the Z-axis 21. The X-axis 23 and Y-axis 22 control the movement of the laser head 31 in a plane perpendicular to the Z-axis 21. The processing material is mounted on the porous base plate 4. The processing material is flexibly processed by the lifting and lowering of the porous base plate 4 and the sliding of the laser head 31. The laser assembly 3 includes a laser head 31 and a laser generator. The laser head 31 includes multiple reflectors. After the laser generator generates high-energy laser light, it is reflected onto the surface of the processing material through the reflectors of the laser head 31. One of the reflectors is mounted at the intersection of the X-axis 23 and the Y-axis 22 and moves with the X-axis 23, so that the laser light is emitted at a right angle at this position and is not affected when the X-axis 23 moves. Similarly, the vertical movement is set on the porous base plate 4, so that the processing material moves and the laser head 31 reflects the laser light.

[0040] The cooling assembly 5 includes cooling pipes, a water tank, and a circulating pump. The water tank and circulating pump are installed inside the auxiliary part 12. The cooling pipes surround the laser generator or are connected to the heat dissipation pipes of the laser generator to cool the laser generator. The filter box 61 includes a filter screen 611, an activated carbon box 612, and a filter element box 613. The filter screen 611 is used to remove larger dust particles, the activated carbon box 612 is used to remove odors generated during the ablation process, and the filter element box 613 performs finer filtration of the dust. The filter element box 613 can be equipped with filter media with smaller pore sizes, or different filter media can be set according to the composition of the dust generated by the cutting material.

[0041] The control module 7 is a PLC control module that controls the logical operation of the laser component 3, the moving axis group 2, the cooling component 5, and the filter fan 62.

[0042] As one specific embodiment of the laser processing equipment provided in the application, please refer to Figure 2 The processing section 11 is equipped with an air pump 64, which is connected to a blow pipe 641. The output end of the blow pipe 641 is located at the laser head 31.

[0043] Overall, by setting up the blowpipe 641, on the one hand, it is convenient to blow away the ablated material in time during the laser processing to avoid affecting the next processing step. On the other hand, the blowpipe 641 blows the ablated material to break it up and make it float to form dust, which is easy for the filter fan 62 to draw away, preventing it from falling on the reflector and affecting the laser reflection efficiency.

[0044] As another specific embodiment of the laser processing equipment provided in the application, please refer to Figure 6Multiple air outlets are arranged in a straight array along the back panel 63. A conversion box 631 is fixedly installed on the back panel 63. A rectangular opening covering the air outlet array is provided on the side of the conversion box 63 near the back panel 63. The side of the conversion box 631 away from the back panel 63 is connected to the upper end of the filter box 61 through a pipe.

[0045] In the specific application scenario, the processing position changes as the moving axis group 2 moves during the processing. By setting the air outlets in a linear array, the air outlets can cover a larger area, which is convenient for dust removal. By setting the conversion box 631, the connection between the air outlet array and the pipeline is facilitated.

[0046] In some feasible embodiments, the conversion box 631 is rectangular, with a rectangular opening on one side and a circular tubular interface on the side away from the rectangular opening, and a connecting pipe.

[0047] As one specific embodiment of the laser processing equipment provided in the application, please refer to Figure 6 and Figure 7 The auxiliary part 12 has positioning holes 121 near the top corner of the upper end, and the processing part 11 has positioning blocks 122 fixedly installed near the top corner of the bottom. The processing part 11 is placed on the upper end of the auxiliary part 12.

[0048] It should be understood that the overall size of the equipment is relatively large. By separating the processing section 11 and the auxiliary section 12, the two parts can be placed independently, which is convenient for use in places with limited space.

[0049] Further, please refer to Figure 6 The processing section 11 is provided with an exhaust plate 201 on the side away from the moving shaft assembly 2. The exhaust plate 201 has a through hole and an exhaust fan is provided at the through hole position. The air outlet of the back plate 63 is connected to the exhaust plate 201.

[0050] It should be understood that by setting up the exhaust plate 201 and the exhaust fan, the processing unit 11 can be used for processing without using the auxiliary unit 12, which further facilitates the installation and use of the equipment and improves its adaptability to the environment.

[0051] In some feasible ways, the positioning block 122 is set as a rubber block, which serves as a support when the processing part 11 is placed alone. The exhaust plate 201 is a rectangular plate with a circular tubular interface. This facilitates the connection of pipes when the processing part 11 and the auxiliary part 12 are set separately, and also facilitates the installation of an exhaust fan as an exhaust port when the auxiliary part 12 is not used.

[0052] As one specific embodiment of the laser processing equipment provided in the application, please refer to Figure 8The Z-axis section 21 includes four lead screws 211 rotatably mounted on the machining section 11. A multi-hole base plate 4 is threaded to the lead screws 211. Each lead screw 211 has a gear 212 at its bottom. The output end of the Z-axis section 21 drive motor is fixedly mounted with a gear 212. The gears 212 of the four lead screws 211 are connected to the gears 212 of the Z-axis section 21 drive motor by the same toothed belt 213.

[0053] It should be understood that by connecting the four lead screws 211 to the same toothed belt 213, the four lead screws 211 move synchronously, which facilitates the lifting and lowering movement of the perforated base plate 4.

[0054] In some feasible configurations, two auxiliary wheels are positioned near the drive motor of the Z-axis section 21, with the outer side of the toothed belt 213 fitting against the two auxiliary wheels. The gear 212 of the drive motor is located on the perpendicular bisector of the line connecting the two auxiliary wheels, so that the wrap angle of the toothed belt 213 at the position of the gear 212 of the drive motor can provide sufficient power. The machining section 11 has a mounting plate above the lead screw 211. The Y-axis section 22 includes two mounting brackets mounted on the mounting plates on both sides. The mounting brackets are equipped with gear 212 and toothed belt 213 mechanisms. The X-axis section 23 is fixedly connected to the toothed belt 213 at both ends. The drive motor of the Y-axis section 22 is a dual-output shaft motor, which facilitates the synchronous driving of the two gear 212 and toothed belt 213 mechanisms of the Y-axis section 22. The X-axis section 23 is also equipped with a mounting bracket, gear 212 and toothed belt 213 mechanism. The laser head 31 is partially fixedly connected to the toothed belt 213. To facilitate sliding, wheels are provided at the connection positions of the laser head 31 and the X-axis section 23 and the X-axis section 23 and the Y-axis section 22.

[0055] As a specific embodiment of the laser processing equipment provided in the application, the auxiliary part 12 is provided with quick-release plates at the positions of the cooling component 5 and the filter box 61, and the processing part 11 is provided with quick-release plates at the positions of the laser component 3 and the control module 7.

[0056] It should be understood that the quick-release plate facilitates the repair and maintenance of the relevant parts.

[0057] In some feasible ways, the quick-release plate can be set as a hinge plate, with a magnetic or flat lock at one end of the hinge plate.

[0058] In some feasible embodiments, a hinge plate is provided on the front side of the processing section 11, located below the upper cover 13. The hinge plate is magnetically connected at one end, making it easy to open the hinge plate and place large processing materials.

[0059] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
